This invention relates to a soil tillingimfollow in the incisions formed by the wheels. plement having ground tools reciprocating On the discs 11a and 116 are crank pins 22a in the direction of the ground level and proand 226. A connecting rod 23 is pivotally vided with stoppers to urge the implement secured to a pin on the beam 18 and jourforwardly. The primary object of this innalled at its other end on the pin 22a. A vention is to provide such an implement havconnecting rod 2a likewise connects a pin on ing stoppers tracking in the soil disturbed the beam 19 and pin 22?). Pivotally secured by the tools. A further object of this into the beam 22 adjacent the juncture of the venticn is to provide a self-propelled implebeam and the plow share is a stepper 25 1o ment of the character described having tracwhich has a foot with a diverging heel 25a tion wheels incising the ground in front of and toe 25?).

The crank pins 22a 15 manufacture is obtained. and 22b-are disposed diametrically opposite.
